Is there any way one can use Visual C or similar DLL's such as which come with National Instruments data acqusition boards to make Origin my data acquisition program? I know that in the past (long ago) there was LabGPIB for a similar concept.

Instead of hardcoded system path, you can code it as #pragma dll(msvcrt, system).

In order to read or write on a port, include the header file:
#pragma dll(c:\WINDOWS\SYSTEM\Msvcrt)
int __cdecl _inp(unsigned short port);
int __cdecl _outp(unsigned short port, int value);
and if short port is the port number
the function:
int a= _inp(port) read the byte on the port
int b= _outp(port,databyte) write |

Here is a link to the PDF:
http://www.originlab.com/PDFs/originc.pdf
This code example will also be included in the Programming Guide Help file in the first Origin 7 patch, due out soon.

Where is the Origin C PDF file? |

Examples for NI-488 GPIB support as well as RS232 support using Origin C are available in the Orgin C PDF.
Origin C can call any DLLs written using Microsoft compilers, so in principle there should be no problem.
